Azimuthal Gamma Module

The Azimuthal Gamma is a probe-based module that provides Azimuthal Gamma measurements and Continuous Inclination.

The Azimuthal Gamma module (or LithoTracker) measurements complement the total Gamma by tracking the lithology and identifying the direction of bed crossing.

A direct drop-in module to connect with the Enteq XXT MWD tool string, the tool can be run in vertical hole to horizontal-well drilling.

Advantages

  • Rugged, field proven design using Enteq and WRT extensive experience in electronics
  • Good wash resistance using quality traceable Nitronic materials sourced and machined using our Enteq’s US machining capabilities and expertise
  • Enteq’s integrated interconnect design for reduced rig-up length
  • Nitronic housing for increased resilence in tough well conditions

Features

  • Suitable for harsh environments with true performance at 175 Deg C and >20000 psi
  • Fully compatible with Enteq XXT MWD system – drop in replacement
  • Integrated interconnect design for shorter length
  • Continuous Inclination measurement
  • RPM measurement
  • 3-axis shock & 3-axis vibration sensor
